Fair enough. Photos also leak much more data points than most people realize. For example, the higher the quality and resolution, the more diseases a skilled doctor would be able to diagnose from it - even ones you don't know you have.

My point is, all those little bits of data that are being collected all the time, by almost every website and program you use, leak all of this and much more. It doesn't "feel" like you're revealing anything important, and yet a full visibility into a week of your browsing history will tell me an order of magnitude more about you than a random photo ever could. A year's worth of your digital footprint will tell me more than your whole photo album. Etc.

(And the worst thing is, when you make and share your photos digitally, companies get both.)
